Title: Improvements in or relating to the separation of liquid mixtures by distillation
IPC: C03B27/04
Filed: 1936-02-06
Abstract: <PICT:0465757/III/1> In the separation of liquid mixtures, particularly alcohol and water, by the addition of an entrainer body, such as benzene, to form a ternary azeotropic mixture in a dehydrating column, the entrainer in the form of vapour is supplied at a level lower than that of the inlet into the same column of the mixture to be separated, the fluids then flowing in countercurrent to each other.  Benzene vapour from air evaporator K is admitted to a column I through a pipe t below a pipe g through which aqueous alcohol vapour issues from a distilling column E in which fermented wine is distilled.  Reflux returns to the column from a condenser V, the watery layer being discharged to a separator P wherein additional water is added to facilitate separation.  The liquids from the mixer P separate in a vessel Q, the dilute alcohol being returned to the distilling column E through a preheater C and the benzene to the vaporizer K.  The wash liquor may be caused to boil under reduced pressure in a boiler F and the vapours, compressed by a compressor R, utilized to heat the vaporizer K, a vaporizer L at the base of the dehydrating column, and the distilling column respectively. Specification 409,053 is referred to.

Abstract: 767,116. Ventilating vehicles. VAUXHALL MOTORS, Ltd. Feb. 2, 1955 [Feb. 9, .1954], No. 3734/54. Class 137 Apparatus for ventilating and heating the interior of a vehicle comprises a casing 1 which is fixed to the dash panel beneath the engine bonnet and has a fresh air intake 4 controlled by a butterfly valve 5, a flap valve 7, hinged to the upper edge of a heating element 6 accommodated in the rear part of the casing, apportioning, in the desired ratio, the air flow passing through the heating element 6 and/or along a by-pass 6a above it. Upstream of the heating element 6 the casing is divided, by a partition 8, into upper and lower chambers 9, 10 which intercommunicate by way of an opening 11 adjacent the heater 6. The chamber 10, containing a centrifugal fan 12, forms a r.e-circulation air duct which has an opening 13 which communicates with the car interior and is controlled by a flap valve 14. The air from the casing is delivered to the car interior through a manifold 3 which extends across the dash panel and has a main delivery opening opposite the driver's seat, smaller delivery openings.at each end (riot shown) and a transverse duct at the top -having openings 32 for directing warm air across the windscreen surface. The apparatus is controlled by two hand levers 16, 20, Figs. 8, 9, the lever 16 being connected to the air inlet control valve 5 which is urged shut by a spring 17. Movement of the lever 16 slightly beyond the shut position operates a spring-pressed button switch 19 which starts the electric motor 15 of the fan 12, the suction of which opens the valve 14 to draw in recirculation air. The heater 6 is controlled by the heat lever 20 which also 'controls the apportioning valve 7, the latter of course being ineffective when the valve 5 is shut and the fan 12 is running. The heat lever 20, connected to the valve 7 by a cable 21, and a spring-loaded lever (not shown) also indirectly controls a spring- loaded valve (not shown) which regulates the flow of engine coolant through the heater 6, a pin 23 on the lever 20 engaging a pivoted arm 24 which is connected by a cable 25 to the water valve. The lever 20 is capable of moving the valve 7 between two extreme positions A and C, the pressure of the pin 23 on the arm 24 being relieved between the extreme position A and an intermediate position B to open the water valve and permit the flow of hot water into the heater 6. To ensure the setting of the two hand levers 16 and 20 each lever carries a toothed quadrant which is engaged by a spring-pressed detent (not shown)-

Title: Improvements in or relating to the generation of electrical impulses
IPC: H03K5/06
Filed: 1941-04-04
Abstract: 581,968. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., LEVY, M. M., and WEAVER, L. E. April 4, 1941, No. 4506. [Class 40 (v)] An arrangement for producing shortened electrical pulses from original pulses comprises a thermionic valve and a delay network whose input terminals are connected in series with the cathode circuit of the valve and whose output terminals are left unconnected, the original pulses being applied to the control grid of the valve and the shortened pulses being taken from the plate circuit. In the form shown in Fig. 7, a time delay network 1 is connected across the terminals x1, x2 of an impedance Z0 in the cathode circuit of a valve 2, to the grid of which an impulse a of steep front is applied. This causes a corresponding impulse to be applied to network 1 which is reflected back as an impulse b which is of the same sign and slightly delayed since terminals y1, y2 are open-circuited. The a and b impulses are combined at x1, x2 and the output taken at Z1, Z2 through a blocking condenser 10 comprises an impulse c of very steep front and of very short duration. Fig. 8 shows an arrangement in which a valve 2 has in its anode circuit an anti-resonant circuit 11, 12 critically damped by an impedance Z0 and delay network 1 with its output terminals y1, y2 shortcircuited. A second delay network 1<1> with open-circuited output terminals is connected across an impedance Z<1>0 in the cathode lead. The circuit without the delay networks would produce steep-fronted pulses from a squaretoppod input a1. Network 11 increases the steepness of the pulse by effecting a sharp cutoff of anode current as in Fig. 7, while network 1 further narrows the pulse by combination with a delayed reflected pulse of reversed sign. Specifications 514,271 and 528,310 are referred to.
